I keep loosing fish. I have two clowns which I have had for over a year but anything else I have put in the tank lasts only a month or two. I bought a green chromis on Sunday and it died last nite. I have no idea y! My parameters are all good just my nitrates are inbetween 5-10ppm. I do weekly water changes using RO/DI water. I just can't wait to get my new tank. It will be alot bigger so hopefully easier to keep my parameters at good levels
